Well if they would keep the same pace as the F35C program and asuming FC-31 is the equivilant of the X-35. we should see them enter service by 2031. My bet is they are gonna be ready before that..Why is the J-31 variant taking so long compared with the J-20 plane?
My guess is that the delay is COVID-related.
Maybe ever considered that J35 has to be operated in an EMALS launch system ? Maybe they were waiting for the EMALS system to be ready? If EMALS never took off, they'd have to start again with the J35 , that'd operate by a ski-jump , which would mean lower take-off weight and speed.If you want to see the original screencap of the announcement by AVIC, it's in this thread.
